Y s'rARR' M. GIBBs,orivroumriaamrna-iivmnrnaivnf TOHCZZZ mama may concern "Be it'known that L STARRM. omega and useful Improvements in Hand Vises,

ofwhich' the following is a specification;

This; invention relates to certain improvements in 'gripping tools of that class having crossed levers and jaws" so I correlated that the jaws moveinnearly parallel planes shaping them to the article in the jaws,

when'bein'g' open or closed and the jawsof; the 'vise are parallel when the jawsare ad justed',\vith a sufficientl'grip tohold flat or" round articles firmly between the jaws;

The jaws of this vise will also shape them-f This hand vise whenfcl'osed on to' flat or" round articles'firstl come's in contact at-the nose or end ofjaw'sf and then as pressure is applied; with thel'sc'rew" the jaws straighten out parallel with each other thereby creating pressure so great that the article held as fast and firm as though it were a part of the vise.- Another advantage that I claim is that because of the great strength of this vise the jaws can be made smooth and will not scratch or mark up gold or silver or similar metals, the

vise being especially adapted to the jeweler,

tool maker, and machinist. v

land vises form a leading type of hand tools of the class herein referred to and such hand vises have been selected to eX-.

selves to the utilization of the features here-.

inafter set forth, and hence reserve the liberty of embodying the improvements hereinafter described and claimed n hand tools, other than those known specifically as hand rises and to all such tools in which said features may be usefully employed.

' ()ne of the important objects of the present invention is to provide atool of the class herein set forth whichwill be of strong durable neat and well balanced construction and which may be most readily and conveniently adjusted to ifit different sizes of articles- Application filed September 6, iaa fi ser iai' nol49s,eao.I-=

foregoing objectsiof the "invention f and others? which will appear from the fol- V lowing descripti'onand accompanying drawf ing"'- "disclosing" the preferred qembodiment:

thereof are bestrsecuredfrom the construetions illustrated in the accompanying .draw- 5 ings', wherein-eFig ure IQ is an elevation of a vise embodying the invention showing the parts'inlooth open and closed position; Fig;

cient pressure of the screw. Thereby add ing to "the gripping power 7 of the jaws.

'Fig.i 2 is an elevation showing a-bise'ction view brmgmg out clearly all the working pointsy v. j

Fig.3 is a longitudinal elevation on a plane. atfright angles to that from which the device is viewed in thejtop of thQViSef' g a F ig. 4 is a longitudinal elevation showing the bottom of ='vis'e' an oppositej view of open 'atth'e same time and paralleh I 1 The toolof the present invention includes and 2 Showing '2 h w :that t'he bqdy'iian r i i andear ikewise two bar members having jaws 2 and 3f fixedly connected to one end thereof; two

or more pairs of crossed, levers 5 and 5" whose forwardends are pivoted to body of I to keep the parts in parallelism with each other while the tool is beingadjusted; in bar 1 at 16 and bar 2 at 16' a tapered-cutout is provided for lever5 to close in when the vise is in closed position; And an adjusting screw 4 which is arranged just rearward of th jaws 2 and 3 and'goes Rough hole bar 1 at rear of jawi2 into a threaded hole of bar 2 at rearof jaw 3. Said screw. having an annular shoulder 11 which is "held in-a retainer 12 which'i's fastened to body member 1 at 14 in. such a way that whenthe screw is rotated the jaws open or close according to the way the screw is turned.

' Like characters, of reference denote like parts in the several views. The adjusting screw 4' alsohaving-acap 'screw 4 which is a safety device preventing the annular shoul-f'. der retainer screw 14: from breaking when a v 2' body section lare integralwith each thejaws are open to their full capacity; The

screw 4 has lever handle-115 whichlniakesit' possible to screw the jaws tight enough to hold work within the jaws. In the -particii-= lar form of the device herein exemplified the other, and the jaw 3 body section 2 are also integral with each other! i The lever Sis 'pivoted at its forward end atthe place marked 6 to thevbody 1 and has its rear end provided with a guide pin or projection 7;

which traverses a slot 10 formed in the, rear end ofthe body section 2; Another lever 5- 1 is pivoted at its forward end I, atgtheplace marked 6tothe body Q and has itsrear end provided with a guide pin or projection 7 which traverses a slot 10 in therear end of body section-1; These two levers are pivoted.

. which will act as pivots or rivets to pin le-l vers to vise will be withinthe spirit and' scopeof the claim. Fromthei'oregoing the v construction operation and, advantages of the present invention will be readily understood, and it will be apparent that changes in the form, construction'and relative arrangement-of the parts 'may be made without departing from the spirit of the invention or theis'cope ofthe-isubjoined claim.

. It will be understood that the part named iii tlie foregoing description and following "claim as the body section is intended arbitrarily to include that part of the device 7 which is back of the screw 4. 1 and 2' which aiseservesas a handle.

Having now describedv the invention what Ibelievetoben'ew, and'de'sire tosecure by Letters Patent, is:

1A, 'Jhand vise comprising ja ws,-each jaw including a'j aw proper and a body'sect'ion, an ad ustingscrew provided with an annular"sh0ulder; facing one of the jaws, cross levers pivoted to each other attheir place of intersection and having one pair of ends'pivotedfto s'ai'd body sections contiguous to'the' Q said: adjusting screw and the other pair of end'spivoted in slots in the opposite ends of the said body sections, a retaining device fasteiied'to' one of the body sections, one end 1 of which'fits over, the annular shoulder of the'adju'sting's'cre to make the top jaw. of the vise follow the annular shoulder of the adjusting screw as the adjusting Screwis rotated to" open the jaws, a lever handle mounted on said adjusting screw for operating the same, a cap screw on the opposite end of the adjusting screw serving as a safety device to pr'event'the breaking of the aini'ul'ar'shoulder retaining device. j

1n testimony whereof I have hereunto set my hand, i
